Bluetooth adapters and hearing aids for Motorola APX radios

Hello, I’m currently working for a fire department and looking for possible bluetooth adapters for my APX4000 two-way radio. I have looked into some adapters ( Motorola APX Bluetooth Adapter with Wireless PTT Button ) but I want to make sure that this works for my setup before I drop money on it.

I currently use Signia pure charge&go, and I have an iPhone 15 that I use the bluetooth function for any devices I can pair that will stream audio to my ears. My hope is that the aids might either pair directly to the bluetooth adapter, or pair to my phone which will then stream to my ears (I have this setup successfully with my EKO stethoscope). My audio is best with streaming and if I can cut out listening to my radio through ambient noise, I will be much more successful.

Does anyone have any experience or success with this? Thank you so much!
